PS3 Demo (CECHH01) Questions?

A friend of mine is offering me a Playstation 3 (Demo CECHH01) that he got when he used to work at a BestBuy here in the US.

The playstation its been sitting there for years and from what i've been told it sits on 2.80FW, my question is can i just upgrade the FW to 3.41 just like a regular console? I was told by this other guy that you cant upgrade those type of PS3's

I might have a few other questions, but lets start with this one first.
